Geographic variation in Leptosphaeria maculans (phoma stem canker of oilseed rape) populations in the UK
(2013-08)
Major resistance (R) gene-mediated resistance against Leptosphaeria maculans is associated with a gene-forgene interaction in which the product of a pathogen effector (Avr) gene is recognised by the product of a host R ...
Effects of host resistance on maturation of pseudothecia of Leptosphaeria maculans and L. biglobosa (cause of Phoma stem canker) in Brassica napus (oilseed rape)
(2013-08)
The stem canker epidemics are initiated in autumn by air-borne ascospores produced in pseudothecia on infected crop debris from previous crops. This study aimed to investigate the effects of cultivar resistance and ...
The potential of temperature gradient plates to measure temperature response in fungal pathogens
(2013-08)
Temperature response curves have been studied for a wide variety of processes in an extensive number of organisms. The temperature response of growth in fungi, however, has rarely been studied across a wide range of ...
Climate change increases risk of fusarium ear blight on wheat in central China
(2013-08)
In this work, a logistic weather-based regression model for estimating incidence of wheat fusarium ear blight in central China was developed, using up to 10 years of disease, anthesis date and weather data available for ...
Leptosphaeria spp. and Phoma stem canker on oilseed rape in China
(2013-08)
In China, the incidence of phoma stem canker observed in pre-harvest surveys from 2005 to 2012 was greater on winter oilseed rape in provinces along the Yangtze River (in May) than on spring oilseed rape in north China (in ...
Comparative epidemiology of Leptosphaeria maculans and L. biglobosa on oilseed rape in the UK
(2013-08)
Phoma stem canker is a major disease problem on winter oilseed rape (Brassica napus) in the UK. The disease is caused by two closely related species, Leptosphaeria maculans and L. biglobosa. Previous epidemiology work has ...
Arable crop disease control, climate change and food security
(2013-08)
Global food security is threatened by crop diseases that account for average yield losses of 16%. Climate change is exacerbating threats to food security in much of the world, emphasising the need to increase food production ...
Epidemiology and spread of Leptosphaeria species (phoma stem canker) on brassicas
(2013-08)
Leptosphaeria maculans and L. biglobosa, cause of phoma stem canker disease of brassicas, are related pathogens of brassicas that were originally considered as one species but occupy slightly different ecological niches ...
Pathogenicity of Leptosphaeria biglobosa to oilseed rape (Brassica napus) cultivars differing in resistance against Leptosphaeria maculans
(2013-08)
Field and controlled environment experiments were done to examine the pathogenicity of L. biglobosa on cultivars with good resistance (carrying the Rlm7 gene) or moderate resistance (carrying the Rlm4 gene) against L. ...
R gene-mediated resistance in Brassica napus that limits asexual sporulation but allows sexual sporulation by Pyrenopeziza brassicae (light leaf spot)
(2013-08)
The phenotype of a form of Brassica napus (oilseed rape) R gene-mediated resistance against the hemibiotrophic plant pathogen Pyrenopeziza brassicae, cause of light leaf spot, was investigated. Using a doubled haploid B. ...
